Description
Technical field
The present invention relates to the release in control and protective switching device, be specifically related to the transmission mechanism in a kind of release.
Background technology
Control and protective switching device is a kind of existing on-off action, can automatically carry out again the electrical equipment of decompression, under-voltage, overload and open circuit protection.Power circuit and motor etc. are carried out to protection, can automatic shutdown circuit in the time that serious overload or short circuit and the fault such as under-voltage occur for they.
As existing patent documentation CN2472341Y discloses a kind of integrated control and protective switching device, it comprises base, main circuit contact group, and electromagnetism transmission mechanism, operating mechanism, interrupter, overcurrent trip, interlocking device, power supply detect relay.Wherein the differential attachment of overcurrent release has respectively and three bimetal leafs of power supply three-phase series and upper guide plate and the bottom guide that driven by bimetal leaf.In above-mentioned control and protective switching device, in the situation that three-phase transships, the heating of bimetal leaf heated element, promote upper guide plate bending left, promote push pedal and make transmission mechanism action, and the slurcam in overcurrent release is moved, slurcam promotes the push rod of operating mechanism, realizes overlond trip; At breakage of circuit phase time, disconnected bimetallic sheet is by cooling then bending to the right, promotion bottom guide moves to right, and two-phase bimetal leaf still makes upper guide plate move to left the in the situation that of current flow heats in addition, result is rotated counterclockwise slurcam under upper bottom guide promotes, make rapidly transmission mechanism move and slurcam is moved, slurcam promotes the push rod in operating mechanism, realizes differential disconnected dropout mutually.
And this mode cannot meet the instructions for use of some special occasions; for example in " design of civil buildings specification ", specify that unexpected power-off will cause than the larger motor of overload loss; should not install overload protection; when distribution line is in the time transshipping; only send alarm signal, do not send trip signal and force power-off.Such as unpredictalbe fault of distribution line and the emergency starting of fire pump when fire in fire-fighting system, all may cause the appearance of overload, in order to win the quality time of handling failure, should not be under the overload situations that this fault level causes and thread off, make staff to judge and to determine accordingly according to on-the-spot at that time special circumstances but need to send alarm signal.Therefore in some special occasions, control and protective switching device will be realized the function of only reporting to the police the in the situation that of overload and do not thread off.
Solve the problems of the technologies described above, need overcurrent release can realize the action that can realize warning function in the situation that of overload and disconnected phase, and operating mechanism can have at overcurrent release generation actuation of an alarm the action of corresponding trigger alarm signal.
In order to solve the problems of the technologies described above, applicant has applied for one section of operating mechanism that is disclosed in the control and protective switching device on patent documentation CN102427000A in 2011, in the time there is overload fault, overload is threaded off and is given the alarm by overload push rod control warning cam; In the time there is over current fault, overcurrent push rod drives overload push rod make to report to the police cam and deflecting cam all to move, and warning cam is threaded off and given the alarm and deflecting cam is threaded off and cut off main circuit.Operating mechanism in this scheme, can realize the alarm non-tripping in the situation that of overload, exports trip signal in the situation that of overcurrent.This operating mechanism will be worked normally, and the overcurrent release that need to be mated can give overload push rod an impulsive force in when overload, in the time of overcurrent to impulsive force of overcurrent push rod.
For this reason, applicant submitted another section of patent application " the signal transport sector of overcurrent trip " July 27 in 2012 to State Intellectual Property Office, and application number is CN201220370230.3, and it comprises differential attachment, alarm mechanism and delayed releasing mechanism.Differential attachment comprises differential plate and guide plate, and guide plate is parallel and be arranged at movably the side of differential plate, and differential plate is connected with bimetal leaf with guide plate and moves under the driving of bimetal leaf, and bimetal leaf is connected with power supply three-phase line; Alarm mechanism, is arranged on the support that is positioned at differential attachment one side, and alarm mechanism coordinates transmission alarm signal with guide plate; Delayed releasing mechanism, is arranged on support, coordinates transmit trip signal with guide plate; The alarm actuating contact of guide plate and alarm mechanism contact contacting early than the dropout contact of guide plate and delayed releasing mechanism.In such scheme, alarm mechanism comprises the first rocking arm for transmitting alarm signal, and delayed releasing mechanism comprises the second rocking arm and the dropout rocking arm for transmitting trip signal.Although said structure can be by the first rocking arm transmission alarm signal, by dropout rocking arm transmission trip signal, but because the first rocking arm and dropout rocking arm are all to move under the driving after sheet metal is heated, it is a kind of simple interaction relation, the power of its output is less, and the overload push rod of operating mechanism and overcurrent push rod need larger impulsive force normally to work, therefore the first rocking arm and dropout rocking arm do not have enough impulsive forces in the time of transmission alarm signal trip signal, if simple is used in conjunction with disclosed operating mechanism in the signal transport sector in such scheme and CN102427000 A, in the time there is overload signal, the power that the first rocking arm produces is not enough to promote the overload push rod in operating mechanism and then controls the dropout of warning cam give the alarm, in the time there is over-current signal, the power that dropout rocking arm produces is also not enough to drive overcurrent push rod to drive overload push rod make to report to the police cam and deflecting cam all to move.
Therefore, in overcurrent release, also need to have transmission mechanism that alarm signal and the trip signal of above-mentioned signal transport sector transmission are transmitted and amplified.And overcurrent release of the prior art, owing to all not considering the function of an alarm non-tripping under overload situations, the transmission mechanism therefore arranging in inside can only all be exported overload signal and over-current signal by a push rod.As disclosed overcurrent release in CN2472341Y, no matter be that overload or overcurrent occur, its transmission mechanism is all finally to come to operating mechanism transfer instruction by the movement of a push rod.
Therefore the transmission mechanism in prior art release can not coordinate with signal transport sector and operating mechanism, the power of the first rocking arm of signal transport sector and dropout rocking arm transmission and displacement cannot be amplified to overload push rod and the overcurrent push rod of rear trigger action mechanism.
Summary of the invention
Technical problem to be solved by this invention is that in prior art, the transmission mechanism in release cannot amplify the power of the first rocking arm of signal transport sector and dropout rocking arm transmission and displacement the overload push rod of rear trigger action mechanism and the technical problem of overcurrent push rod, and then provides a kind of the first rocking arm of effectively amplifying signal transport sector and power that dropout rocking arm transmits and displacement and the transmission mechanism of the release that can coordinate with operating mechanism.
